Occur when two or more activities follow a single node.

A network diagramming technique in which activities are represented by arrows and connected at points called nodes to illustrate a sequence of activities

The series of activities that determine the earliest time by which the project can be completed; it is the longest path through the network diagram and has the least amount of slack or float

A method of scheduling that takes limited resources into account when creating a project schedule and includes buffers to protect the project completion date

Critical Chain Scheduling

Elements of a three point estimate

OptimisticMost Likely

Pessimistic

The amount of time an activity may be delayed without delaying a succeeding activity or the project finish date

A network diagramming technique in which boxes represent activities

PDM

Precedence Diagramming Method

The additional time added before a projects due date to account for unexpected factors

An occurrence when two or more activities follow a single node on a network diagram

A schematic display of logical relationships among, or sequencing of, project activities

The dependencies that are inherent in the nature of the work being performed on a project

Quantitative risk analysis technique that provides a probability distribution for outcome values for the whole project

The dependencies that involve relationships between the project and non-project activities

Additional time to complete and activity, added to an estimate to account for various factors

A tabulation of activities to be included in a project schedule

The number of workdays or work hours required to complete and activity

Information that provides schedule-related information about each activity, such as predecessors, successors, logical relationships, leads and lags, resource requirements, constraints, imposed dates, and assumptions related to the activity

The actual amount of time spent working on an activity PLUS elapsed time

A distinct, scheduled portion of work performed during the course of a project

A management philosophy that states that any complex system at any point in time often has only one aspect or constrain that is limiting its ability to achieve more of its goal

Work expands to fill the time allowed

An estimate that includes an optimistic, most likely, and pessimistic estimate

A technique that uses project characteristics (parameters) in a mathematical model to estimate project costs

aka. Analogous Estimates

The estimates that use the actual cost of a previous, similar project as the basis for estimating the cost of the current project

A standard format for displaying project schedule information by listing project activities and their corresponding start and finish dates in a calendar format

When an activity can overlap a preceding one

What can go wrong, will go wrong

Additional time added before activities on the critical path that are preceded by non-critical path activities

A network diagramming technique in which activities are represented by arrows and connected at points called nodes to illustrate a sequence of activities

A network diagramming technique used to predict the total project duration and show the amount of schedule flexibility on the network paths within the schedule model

A schedule compression technique where you do activities in parallel that you would normally do in sequence

When a resource works on more than one activity at a time

A network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates

PERT

Program Evaluation and Review Technique

A significant point or event in a project

Cost estimates created by estimating individual activities and summing them to get a project total

The starting and ending point of an activity on an activity on arrow network diagram

aka. Top Down Estimates

The estimates that use the actual cost of a previous, similar project as the basis for estimating the cost of the current project

A time-phased budget that project managers use to measure and monitor cost performance

The sequencing of project activities. Relationship between activities

Work that is done in support of operational, functional, or project performance. Tasks are not part of the schedule (activities are shown on the schedule). Tasks include many management functions such as things done to manage the team, run a production line, or build relationships

when an activity requires a gap in time before it can start

A technique for making cost and schedule trade-offs to obtain the greatest amount of schedule compression for the least incremental cost

A situation where two or more nodes precede a single node on a network diagram
